To all whom it may concern:

Be it known that 1,,Fnnnrui1c1c C. TAXIS, citizen of the United States, residing at St. Louis, State of Missouri, have invented cer-v tainnew and useful Improvements in'Con- ,crete Floor Constructions, of which the fol- In the drawings, Figure 1 is a vertical sectionof a concrete floor showing my invention applied thereto, thesection being on the line 11 of-Fig. 2, and the concrete being shown dotted; Fig. 2 is a section at right angles to Fig. 1 being a section 011 line 2-2 of Fig. 1; Fig. 3 is an enlarged section on the order of Fig. 1, showing the concrete in full; Fig. 4 is a vertical section online 44.of Fig. 3; Fig. 5 is a erspective of one of thetrarisverse tie rnem ers'; Fig. 6 is a pers ective of one. of the. ties or anchors, and ig. .7 is a modified form of tie member showing 'the anchor and gage leg integral therewith.

The obj set of my invention isto introduce into a concretefloor construction a structural detail which shall not only serve to properly space and tie the metallic reinforcmg and supporting bars for the concrete, but shall at the'same time serve as a gage for the construction of the boxing into which the cement corn osition is poured around-the bars previous y spaced and ositioned. WVith my improvement any. shifting of thereinforcing members from the positions they are intended to occupy is impossible, a thorough tying therefore is insured, and a uniform construction can always be depended on.

The advantages of the improvement willbe, better a parent from a detailed descrip} tion of the lnvention, which 'is as follows; Referring to the drawings, P, P, represent oonjrete (or other) illars'for the support of the ooncretei'floon't e latter .being made up of suitable oeinent com osition O, and series of support'f and rei orcing bars or members a, bre fictively, having up-turne'd ends a, 11', respectively, thesaid members forming the supports for the floor, the ends thereofresti-ng directly on the'pillars P where the latter are resorted to, or on I'-bea1n's or e uivalent structural. members (not here 1 uslegs' 4, which, in the completed trated as they are fully understood in the art). The bodyportions or main ortions of the members a, b are disposed'in t 1e same horizontal plane at equal distances from the opposite faces of the completed floor as'shown,

the cement being as well understood temcross spacing-members or tie-bars which in" the preferred form of my invention are in the shape of metal strips 1, provided with pairs of slots or openings 2, 2, through which are inserted the arms or tongues 3, 3, of the. pieces or, oor depend, members a b. The," tie-bars are conneote to the members a,

substantially U -shaped spacing below the reinforcin by folding the tongues 3, 3 around the members as shown in the drawings' Thusthel; members a, b are superposed-directly .over' the tie members 1, the spacing le s or'pieces 4 serving to space thereof of the, oxing'B; a

uniform distance from the reinforcing meme bers so that these legs serve as gages which determine the depth of the concrete below the planes of the reinforcing members, the

bases of the le s coming in contactwith the boxing as the atter is undergoing construction, and coming flush with the under surface of the concrete portion of the floorwhen the latter is finished." The depth of insertion of the arms 3 into the openin s 2 is limited by the shoulders 5, 5, whic bear against the solid portion of the strip 1 beyond-each opening. The arms 3,13, and le 4 are stamped from a single sheet of-meta and bent into the form .asshown (Fig. 6), subserving the double function of anchors for securing the spacing or tie-members I to the reinforcing members a, bf, and as spaoin pieces or ages for regulating the depth 0% cement be owthe plane of dispositionof the reinforcing members. I r

In the form of'the. invention 'smfar de scribed, the anchors and spacing legs con-- stitute a, separate piecefrom the tie member sides of the lon 1, instead of being disposed along said cen- 1, but in the modification shown in Fig. 7, I the tie member 1' is provided with bonds 4 on either side of whlch the arms 3 3 are severed or cut from the body of the strip, so that the anchors, and spacing legs or gages are integral with the tie member. The same result is attained with the modified form,- the construction being virtually the same as in the first form described, except that the arms 3 3 occupy positions on opposite itudinal center of the strip tralline.

By concrete floor constructions, I of course wish to include any and all floors or walls of a composite character, that is, those composed of composition, concrete, cement reinforced by metal, the term conerete being herein used in a very broad sense. It is obvious too, that the members 1 need not necessarily be at right, angles to the reinforcing members a, b.

Having described my invention what I claim is:

1. In combination with a reinforcing member ofa concrete floor, atie member or strip having pairs of openings, anchor pieces composed of'pieees of metal 'bent into a U-- shaped form and see,

l a portion of the anchor passed with their arms through said openings, means for limiting the depth of insertion of the arms whereby iece is left projectmg below the tie mem er and forming a age or leg, the free ends of the arms being -fient around the reinforcing member, substantially as set forth.

2. In com ber of a concrete floor, a tie memberv or'strip having pairs of openings, anchor 'ieces composed of single pieces of metal ent into a U-shaped form, and terminating in reduced arms passed through the openings aforesaid, said arms be' bent around the reinforcing member, aimi g! armsgand hardly airline anchor for limiting the depth'loif openings offlfihe rt'ielmember, the portion proi'ecting bellow tfihe Hatter serving as a eg for :agaiinst the roof of the oxing over which ltlhe concrete is poured, substantially as set fo v V In testimony whereof I aflixmy signature, in presence of two witnesses.
